What Does Code P0052 Mean This code is seen when the Engine Control Module (ECM) tries to control the heater control circuit for Bank 2 Sensor 1 and finds high voltage present. The heater is an integral part of sensor function that is used to heat the oxygen sensor to operating temperature until the vehicle warms up. Oxygen sensors must be at operating temperature to provide accurate readings to the ECM for air fuel ratio control.
